CHlLLED-CAR-WHEEL BORING AND TRUING MACHINE.

SPECIFICATION forming part of Letters Patent No. 283,367, dated August 21, 1883.

. Application filed July/'12, 1982. (No model.)

To all whom t indy concern.:

Be it known that I, WM. P. BxncLxY, a citizen of theUnited States, residing at Chicago, in the county of Gool: and State of Illinois, have invented a new and Improved Chilled- Car-Vifheel Boring and Truing Machine, of which the following .is affull, clear, and accurate description.

My invention relatesto machines for boring and truing the periphery of chilled car-wheels atene and the Sametime; and my improvements consist Vin providing apparatus whereby the chilled can-wheels can be bored by the boring-tool and trued on the periphery by the abrading-wheels withthe greatest degree of Y speed and convenience, as more fully described in the annexed specification.

l.Similar letters of reference indicate corresponding parts throughout the entire iigu res.

A longitudinal sectional eier-*ation of my improved machine is shown at Figure l, anda pian view of the saine is shown at Fig. 2. Fig. 3 is an end elevation of the machine, looking from the let-hand side of lFig. l, and Fig. L iis also an end elevation of Fig. l, looking from the iight-hand side of same. Fi g. 5 presents detail views of the base of double standard V and tail-piece V', with the screw, nut, and slide-blocks pertaining thereto.

The bed-plate A is in the form of a cross,

and supports the superstructure of the entire machine. The driving head-stock B has a spindle, B, from one endoi which a face-plate, i B, is secured. The said face-plate supports the car-wheel G and carries the car-wheel around with-it in its revolutions. The pedestal l) supports the boring-head D', that is used for boring out the center of carwheel to the necessary size to conform to the dimension of a car-wheel axle. To the hollow spindle B is also attached a Ascrew-wheel, E. The hollow spindle B', face-plate B, and screw-wheel E are given a slow revolving motion by the action of the screwA E', acting upon the teeth oi' screw-wheel E. The belt-pulley E gives the required motion to the spindle or shaft of screw E. The abrading-wheels F are given a The faceplate B has a cone', G, that is made to correspond tothe inside conical shape of the rim of car-wheel. The two circular rings of rubber I are placed concentrically with each other and press close to the web of car-wheel. The face-plate has a block, J, that is covered with rubber on the face next to the web of carwheel, and the said block is set up as required by the set-screws J formed the entire circle efface-plate or merely put in in sections. The block J, having a pliable material on its face next to the web of carwheel, acts as a driving-dog to the face-plate, and the car-wheel is thus carried around with the face-plate in its revolutions.

The vacuum-.cylinder H has a piston and piston-rod and inlet and outlet air-valves at'each end of cylinder. r[he piston of cylinder H is given a reciprocating motion by the action of the belt-pulley H and connecting-rod H. A pipe, K, connects each end of vacuum-cylinder H to the hollow spindle B of driving headstock B. The core of spindle B also connects by one or more ports, K, with the face-plate B.

ported at the inner end by the bush O. The

pipe l? has its inner end closed, and both ends of said pipe are air-tight, so that no air will be admitted to the core of spindle B by the joints of said pipe. rIhe spindle N of boringhead D is given aquick revolving motion by the action of the belt-pulleys Q and bevelgearing Q. The spindle N is made to move forward, when revolving, by the small belt-pulleys B., giving motion to a screw, R', and screwwheel R, that is placed upon the feed-screw spindle S, that passes through the back end of The block J can be` IOO velocities the spindle N and boring-rod N will be taken gradually forward asY the said spindles are revolving.

The handle S' is for the purpose of placing the screw R in 'gear with the screwwheel R, or out of gear, as occasion requires. Vhen the said screw and screw-wheel are out of gear with each other, the spindle N can be run back or forward by turning around the hand-wheel S S. The hand-'wheel T is connected with the screw T', and as the hand-wheel T is turned around, the entire boring-head D' is moved back or forward, according to the movement of the said hand-wheel.

The columns U 'support the slide-rests, which permit the abrading-wheels F to be moved in parallel directions with the slides of said rests. rIhe top slide of each rest has a double standard, V, that revolves around a boss cast upon the slide-plate V" oiA top slide, and the abrading-wheels F are supported by the double standards V, the spindles of the abradingwheels working in the journal-boxes of said standards. Each double standard Vis also furnished with a tail-piece, V', that is connected to the circular side of double standard by two T-headed bolts working in a groove formed upon the circular side of said standard.

The tail-pieces V' are each furnished with a nut, Ythrough which work the screws W. The nut Y has projecting from opposite sides bosses orj ournals, aroundwhich turn the slideblocks Y. The .slide-blocks Y' can only move in the direction of the length of the tail-pieces V', as they are con'ned by the grooves formed upon the upper and lower faces of said tailpieees. rlhe tail-pieces V also have an oblong hole on thel sides for clearance for the screws W. When the hand-wheel VV' is turn ed around, it turns the screw W and moves thev nut Y along on the screw. As the nut Y is moved it compels the tail-piece V' to move in the same direction, for the slide-blocks Y are pivoted from the nuts Y, and are also conined by the grooves on the upper and lower faces of the tail-pieces V. The grooves in the tailpieces allow of the slide-blocks Y to move back and forth in the direction of the length of tailpieces, and the bosses of nuts Y allow the slide-blocks Y' to turn to any angle that the tail-piece is placed at by the changing of the position of the nut Y on the screw W'. As the hand wheel W is ,turned around it is the means of changing the position of tail-piece V', and through the tail piece the double bracket V is made to revolve around the boss cast upon the slide-plate V", and to which it is secured by a bolt and nut. The bolts that secure the tail-pieces V to the double standards merely allow of the range to be increased that the said standards can be turned around to without requiring to make the tail-pieces V and screws W unnecessarily long or inconvenient;

The hoppersy X convey the refuse that is produced bythe abrading-wheels acting upon the periphery of car-wheels to the pipes X', which are connected to any suitable mechanism used for conveying refuse to any desirable place.

Having described in detail the different parts of my improved chilled-car-wheel boring and truing machine, the principle and action are as subsequently described.

A car-wheel, when placed in position on the face-plate of machine, is supported by the cone G, fitting into the conical-shaped part of the rim of car-wheel, and the circular rings of rubber I, bearing upon the web of the car-wheel, separate the air coniined between the said rubber rings, car-wheel, and face-plate from the outside air, for the car-wheel, when placed close up tol the cone G, also compresses the '.said rubber rings I to an oblong shape, and

the valve of pipe K,v that connects with the vacuum-cylinder H, now being opened, the piston of vacuum-cylinder H pumps out the air confined by the rubber rings between the faceplate and web of car-wheel. Consequently for a considerable portion of the areaof the earwheel there is a vacuum formed between the face-place and car-wheel, and the pressure of the atmosphere, acting upon the reverse side of carwheel, presses against the same kand holds the car-wheel onto the cone G of faceplate with a force or pressure equal to the toA tal amount of vacuum that is vacquired by the exhausting of the air from between the `faceplate and car-wheel. The pressure thus eX- erted by the atmosphere against the car-wheel, and holding the car-wheel firmly onto the cone G of face-plate, is amply sufficient to maintain the car-wheel in position on face-plate, so as to permit the car-wheel to be operated upon by the boring-tool and abrading-wheels of the machine.

The safety-disk L and ring L can be used in conjunction with the vacuum-cylinder H, or independent of it, so that a car-wheel can be bored out at the center by the boring-head D', and trued up on the periphery by the abrading-wheels by the use of the said disk L and ring L', holding the car-wheel Jfirmly onto the cone G of the face-plate, for when the setscrews of ring L' are pinched up tight to `carwheel the ring L is at the same time at liberty to revolve along with the car-wheel and face-plate. The cone G, holding the car-wheel in its proper position, and the' block J havling a rubber face next to the web ofca-r-wheel,

acts as a driving-dog to the. face-plate and compels the car-wheel to revolve precisely along with the face-plate in its revolutions, thus allowing the truing and boring of the carwheel to be done with speed and precision. The disk L and ring L', as used in conjunction with the vacuum-cylinder H, are more for thepurpose of safety, to prevent the car-wheel falling off the cone G under any carelessness of the operator of the machine.
